A fabric softening agent and preparation method thereof

Abstract

The invention discloses a fabric softening finishing agent and a preparation method thereof. The preparation method comprises the following steps: dissolving 3-[3-(2-H-benzotriazole-2-yl)-4-hydroxyl-5-tert-butylphenyl]-acrylic-polyethylene glycol 300 ester in an organic solvent to form a solution, then adding epoxy silicone oil and a catalyst into the solution, stirring and reacting for 8 to 10 hours at 70 to 80 DEG C in a nitrogen or inertial gas atmosphere, removing the organic solvent in a rotary steaming manner, and obtaining the fabric softening finishing agent. The fabric softening finishing agent disclosed in the invention has the characteristics of good hydrophilic property, more firmness in combination in a form of chemical bonds when acting on the fabric, more washability, excellent softening effect, no yellowing, smoothness, and good antistatic performance.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a fabric softening and finishing agent and a preparation method thereof. Background technique [0002] With the rapid development of our country's social economy and the improvement of people's living standards, there are new requirements for clothing. It is no longer a simple requirement for fabrics to be hygroscopic, breathable, and comfortable to wear, but also to be soft, smooth, and elegant. style of. Soft finish agent arises at the historic moment exactly under this situation. Softeners are a class of chemical substances that can change the static and dynamic friction coefficients of fibers. When the coefficient of static friction is changed, the hand feels smooth and easy to move on the fiber or fabric; when the coefficient of dynamic friction is changed, the fine structure between fibers is easy to move with each other, that is, the fiber or fabric i...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the defects in the prior art, the present invention provides a fabric softening and finishing agent and a preparation method thereof, the preparation method is simple and easy, the raw materials are readily available, the price is low, the requirements for reaction conditions and equipment are not high, and it is suitable for industrial production; The fabric softener prepared by the preparation method overcomes the high price of ordinary amino silicone oil in the prior art, the fabric will be hydrophobic after finishing, the fabric will turn yellow after being irradiated by high temperature or ultraviolet light, and the emulsion is prone to oil floating Or the defect of sticking roller phenomenon, it has good hydrophilicity, and when it interacts with the fabric, it will be more firmly combined in the form of chemical bond, more washable, better softness, no yellowing, smoothness, and good antistatic properties
